Abstract:Median-crossover crashes are among the most hazardous events that
can occur on freeways, often leading to serious injury or death. In recent
years, high-tension cable median barriers have emerged as a cost-effective alternative to conventional barriers in preventing such crashes.
MDOT began installing them on state freeways in 2008. This research
project confirmed that cable median barriers are effective at reducing
crossover crashes and improving freeway safety in Michigan, produced
guidelines to help identify the best locations to install them, and
developed content for public outreach materials explaining their benefit.
